Microsoft Corp. is working with the OPC Foundation to enable almost any IIoT scenario using interoperability between the millions of OPC UA-compliant applications and equipment. Microsoft will enable IIoT users to connect manufacturing equipment and software with extended support of OPC UA's open-source software stack. Microsoft’s extended support for OPC UA spans its IoT offerings from local connectivity with Windows devices to cloud connectivity via Microsoft Azure. Integration with Azure IoT allows customers to easily send OPC UA data to the Azure cloud, as well as command and control OPC UA devices remotely from the Azure cloud.

Our panel of experts explore best practices for dealing with buildup on chemical seals of a differential pressure flowmeter.

Q: We have a venturi flowmeter with 3-in. flanged pressure taps and flanged chemical seals with capillary tubes in a 44-in. vertical pipe (Figure 1). The fluid is hydrocarbon (polymeric) gas. The problem is that the chemical seal diaphragms often…

A Control Design reader writes: We have several temperature, pressure and flow sensors on a new medical-device cleaning skid that we are developing. These instruments are connected to a PLC as 4-20 mA inputs, and there is also a 4-20 mA output used to control a pump motor speed. A recent failure of a flow sensor brought the process skid instrumentation to my company's quality manager's attention. He asked how we know that the temperatures, pressure and flow are accurate, and how do we know that we are cleaning properly.
I've been tasked to write a procedure for troubleshooting, calibrating and testing the 4-20 mA instruments on the skid. I can probably stumble through this, but what are some best practices for troubleshooting the analog…

2008

As the economy crashes, process automation is poised to ride it out. Walt Boyes speaks with ARC Research Directors Larry O'Brien and Craig Resnick on the state of the process automation economy, and the Control/ARC Top 50 automation companies.

This informative webcast, presented by experts from Microsoft, Aberdeen and Iconics, will review nextgeneration software analytics solutions built on the latest open, scalable technologies. Youll learn how to rapidly integrate new and existing systems into a unified management platform, resulting in enormous savings and improving the bottom line. Join us at 2 p.m. EST December 11, 2008. A questionandanswer period is included at the end of the presentation. » Register Now

Cybersecurity is one of the pillars of protecting our critical infrastructure. It was profiled in one of the November Special Edition stories, and Bob Mick, ARCs vice president of enterprise systems joins Controls Walt Boyes to put cybersecurity in perspective  and offer agreement and disagreement with what the article said

Controls Walt Boyes reports on how end users are using field instruments, analyzers and final control elements. Wired or wireless, this is where the rubber meets the road.

Matt Willmott discusses the top business issues process manufacturers are facing today and how an integrated main automation contractor approach can help overcome those challenges and ensure a smooth transition from project into operations.

Harry Sim left Honeywell for Cypress Envirosystems (a subsidiary of Cypress Semicon) two years ago because he had an idea that needed Silicon Valley innovation and technology. Now, with Honeywells help, Sims wireless gauge readers are giving new life and a digital flair to outmoded dial gaugesat Genentech and other pharma sites. Pharmaceutical Manufacturing Senior Editor Paul Thomas spoke with Sim at the recent ISA 2008 show in Houston.

Editor in chief Walt Boyes talks about effective alarm management processes. Over the past 50 years many process industry disasters could have been avoided if only the proper alarm systems had been in place. The switch of alarm management systems from panel walls to display screens and DCSs resulted in system operators' loss of visual pattern recognition. This switch caused the newer generations of alarm operators to develop tunnel vision. Meanwhile lack of careful alarm rationalization causes them to be inundated with too many alarms, making it impossible to respond to the important ones. Watch this 5-minute video and learn how to design an alarm system that contributes to your plant's "inherently safe" lifestyle.

October's cover story in Control is the search for the One True Network, as chronicled by John Rezabek, our intrepid On The Bus columnist. Walt Boyes, Control's editor in chief talks to Larry O'Brien, research director for process automation for ARC Advisory Group about fieldbus in this month's edition of the Control/ARC Monthly Podcast Series.

Control contributing editor Rich Merritt conducts a wide-ranging interview with ARC Advisory Group principal analyst John Blanchard on a variety batch-related topics and trends. The interview is a follow-up to Merritt's "Domino Theory" cover article on batch processing in the September 2008 issue of Control. The two discuss the ISA88 standard's history, whether the word "batch" can be mentioned to continuous control users, how ISA88's documentation procedures can help users and where ISA88 and ISA95 may be headed in the future.

Human-machine interfaces (HMIs) are increasing in number, variety, resolution, sophistication and related computing power, and so are becoming all-pervasive in most process applications. To help make sense of this rapidly changing market, Jim Montague, Control's executive editor, presents the results of Control's latest Market Intelligence Report on HMIs. Respondents reported on how they use HMIs to interact with their plants control systems, the age of their existing HMIs, their visual presentation preferences and on how well their HMIs handle alarms.

ARC wireless expert Harry Forbes joins Editor in Chief Walt Boyes in a far-ranging discussion of wireless based on Control's August cover story.

This Special Report from the Process Automation Media Network, sponsored by EZAutomation, focuses on how Control readers use remote HMI systems and what they like--and don't like--about them. Walt Boyes reports on a special survey done in early August of 2008 of over 225 Control readers.

Featuring the latest in multimedia and animation technology, this special report from the Honeywell User Group Americas Symposium includes more than 20 articles and presentations as well as eight streaming videos and audio podcasts--many of which have never before been published. Witness Honeywell's latest technology roadmaps and learn best practices from expert users on topics ranging from alarm management to wireless.
